Static Device

Any part of the device that does not move significantly.

Static Device


Components of wind or marine renewable energy devices such as the foundation, stationary turbine blades, power cables, anchors, or mooring lines can potentially cause harm to animals through collision. However, the consequences of an animal colliding with a stationary device will almost certainly be small as compared to a collision with a moving blade. The likelihood of collisions with stationary devices is dependent on the bathymetry (in the ocean) or terrain (on land), where the devices are located in a waterbody or hillside, in relation to animal migratory corridors or passages, and during inclement weather (for wind turbines).  As commercial arrays are deployed, it is possible that the likelihood of collisions with stationary parts of devices will increase over that of single devices. The physical presence of one or many devices may cause animals to avoid the area, potentially resulting in loss of foraging, breeding, rearing, or resting habitats. Fish may be attracted to a device to feed on algae or to swim in an eddy, while bats may be attracted to a device to feed on insects that are attracted by the light, both of which may place them at higher risk for collision with dynamic portions of the device. Mooring lines that anchor floating devices to the seafloor could also confuse or entrap large marine animals like whales, causing panic and potential injury or increased predation.
